What Is The Effect Of Raw Materials On Pellet Hardness?

              During the pelletizing process of feed pellet mill, all aspects of raw materials will affect the hardness of pellets, including the formula and treatment process of raw materials, today we will talk about how raw materials affect the pellet hardness of pellet mill.
              In the grinding process, the crushing size of the raw material is the decisive factor for the hardness of the pellet. Generally speaking, the finer the raw material particle size is the easier it is to paste, the stronger the adhesion in the granular material, the less crushing, the greater the hardness. The particle size distribution of the crushing is favorable to the particle size and appearance quality, and can ensure the proper hardness of the product and lower crushing rate.
            Through the pretreatment of raw materials, it is possible to kill some bacteria and eliminate harmful substances, so that the raw materials are denatured and the starch is completely pasted. The pasted starch has a significant effect on the hardness of the granule. Due to the greater degree of pasteurization of granular materials, the hardness of granules is greater, and the hardness of granules must be reduced by other methods.
